  1. 1. Submitted by: Bhim Pandey R-2015-AGR-03 M Department of Agronomy EFFECT OF DIFFERENT INOCULATION METHODS IN LEGUMES PRODUCTION INSTITUTE OF AGRICULTURE AND ANIMAL SCIENCE PG campus, kritipur, kathmandu
  2. 2. INTRODUCTION  Legumes are unique plants which have the ability to work with certain strains of bacteria (Rhizobia) to gather atmospheric (N2) nitrogen from the soil atmosphere and convert it to useable ammonia (NH3) nitrogen.  The ability of symbiotic fixation may offer an opportunity to improve nitrogen status of the soil and crop productivity under rainfed conditions  Plant-growth-promoting bacteria affect plant growth directly are by the fixation of atmospheric nitrogen, solubilization of minerals such as P, production of siderophores that can solubilize and sequester iron, or production of plant growth regulators that enhance plant growth at various
  3. 3.  application of Rhizobium inoculation alone or in combination with P and N significantly increased nodulation of soybean  Phosphorus and nitrogen play specific role in symbiotic N2-fixation through their effects on nodulation and N2-fixation process  Inoculant is applied to the seed by Dusting, slurry, seed coating  Innoculation has several advantages, such as protection of Rhizobia against low pH soil, desiccation, acidic fertilizers, fungicides or insecticides Objective:  TO know the effect of different inoculation methods in legume production
  4. 4. Review Of Literature Production and consumption trend of legumes in the world  Average pulses contribute about 3% of total calories consumed in developing countries, ranging from 4% in Sub Saharan Africa, 3% in South Asia and Latin America and the Caribbean, 2.5% in Middle East and North Africa and less than 1% in Central Asia region  The world average per capita consumption of six focused food legumes (dry beans, chickpea, cowpea, lentils, faba bean and pigeon pea) comes to about 6.8 kg/year in 2006-08, which is in the ballpark of the world average per capita consumption of all pulses of 6.5 kg/year in 2005-07.  Average per capita consumption of other pulse crops—faba bean, pigeon pea and lentils range from 0.5 to 0.6 kg/year in 2006-08

Rhizobium and legumes Legumes Rhizobium strain pea, lentil, faba bean, chickling vetch Rhizobium leguminosarum Chickpea Rhizobium ciceri dry bean Rhizobium phaseoli Soybean Bradyrhizobium japonicum alfalfa, sweet clover Rhizobium meliloti Clover Rhizobium trifolii Fenugreek Rhizobium spp. Strain RGFU1 Source: Choudhry.

  6. 6. Inoculation and production  The aim of inoculation is to achieve a high proportion of nodules formed on the target host legume occupied by an efficient strain of Rhizobium (Evans et al., 1989; Thies et al., 2001)  Ali et al.,2004 concluded 57 kg P2O5 + 22 kg N/ha + inoculation produced significantly the highest grain yield/ha, number of nodules/plant and net return  Inoculation of soil and seed with Rhizobium significantly influenced seed protein content, N-content of shoots and roots of lentil and soil, which consequently led to improved soil fertility and can reduce the production cost of next crop through reduced input in the form of nitrogen fertilizers, which in turn also minimize the health hazard effects.( Ahmed et al.,2007)  The cross-inoculation of legumes of agricultural importance with rhizobial isolates from wild legumes resulted in an increase in dry matter and total nitrogen
  7. 7. Process of nodulation and N2 fixation  Root nodulae bbacteria can gain entry to their hosts through root hair penetration and infection thread formation, via wounds or site of lateral root emergence or by penetration of root primodia found on the stem of plant such as Sesbania and Neptunia(Stem nodulation)  Infection  Penetration  Infection thread formation  Nodule formation
  8. 8. Inoculant Application  Dusting  Slurry  Seed coating  the indirect application method the inoculant is applied to the soil beneath or alongside the seed
  9. 9. Techniques of inoculation  Seed inoculation  Dusting  Lime-Pelleting  Granule  Soil inoculation
  10. 10. Materials And Methods This term paper was prepared by collecting the information about the related topics from the different secondary sources.  books,  magazines,  annual reports,  proceedings  krishi Dairy-2073,  Krishi magazines,  Master’s and PhD thesis,  class notes and the research papers
  11. 11. Results And Discussion  Yield increases range from 10 – 100% depending on specific soil conditions. On soils with average fertility, increases in yield usually vary between 15-25%.  Rhizobium inoculation also Increases soil nitrogen for future crops it is because Generally the amount of nitrogen fixed by the plant will be about 75% of the total nitrogen used in the growth of the plant  Nitrogen fixed by legumes will also vary depending upon species, suitable bacterium population, soil nitrogen content, soil fertility, moisture and temperature  A two-times increase in nodules number was recorded in the combine treatment of Rhizobium inoculation+90Kg P2O5/ha+25 Kg N/ha this will help in increasing yield of crop. Dry weight and nitrogen contents of Vigna mungo plants increased significantly in response to cross inoculation as

  13. 13. Conclusion  There is benefit of inoculating legumes with Rhizobium on increasing grain yield, plant biomass and nutrient quality of the products.  The different inoculation techniques have importance on their own place but most popular and easiest method of inoculation is seed inoculation method
